- 八、運行界面
一、類微信界面的功能
1.可展示出四個可切換界面：微信、朋友、通訊錄、設定；
2.上方欄標題居中，界面中間顯示內容，內容隨下方欄的選擇而切換，下方欄可點擊切換，點擊過的界面的圖示為綠色，沒有點擊的界面的圖示為灰色；
3.主要從top、bottom、中間布局以及MainActivity四個方面分析，
二、top布局
在res檔案夾的layout中新建top.xml，將標題欄的內容居中，并將背景色調為黑色，文字調為白色，
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="65dp"
android:gravity="center"
android:background="#000000"//顏色編碼都是六位
android:orientation="vertical">
<TextView
android:id="@+id/textView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="@string/app_name"
android:textColor="#ffffff"
android:textSize="20sp" />
</LinearLayout>
三、bottom布局
1.將圖示檔案夾粘貼到drawable中；
2.在res檔案夾的layout中新建bottom.xml，拖入TextView拖入ImageButton后會呼叫drawable，選取所需的圖示；
3.復制粘貼四個并調整水平平鋪布局，
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="80dp"
android:background="@drawable/bottom_bar"
android:orientation="horizontal"
android:baselineAligned="false">
<LinearLayout
android:id="@+id/id_tab_weixin"
android:layout_width="0dp"
android:layout_height="match_parent"
android:gravity="center"
android:layout_weight="1"
android:orientation="vertical">
<ImageButton
android:id="@+id/id_tab_weixin_img"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
android:clickable="false"
android:contentDescription="@string/app_name"
app:srcCompat="@drawable/tab_weixin_pressed" />
<TextView
android:id="@+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="微信"
android:gravity="center"
android:textColor="#ffffff"
android:clickable="false"
android:textSize="15sp" />
</LinearLayout>
<LinearLayout
android:id="@+id/id_tab_frd"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical">
<ImageButton
android:id="@+id/id_tab_frd_img"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
android:clickable="false"
android:contentDescription="@string/app_name"
app:srcCompat="@drawable/tab_find_frd_normal" />
<TextView
android:id="@+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="朋友"
android:gravity="center"
android:clickable="false"
android:textColor="#ffffff"
android:textSize="15sp" />
</LinearLayout>
<LinearLayout
android:id="@+id/id_tab_contact"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical">
<ImageButton
android:id="@+id/id_tab_contact_img"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
android:clickable="false"
android:contentDescription="@string/app_name"
app:srcCompat="@drawable/tab_address_normal" />
<TextView
android:id="@+id/textView3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="通訊錄"
android:gravity="center"
android:textColor="#ffffff"
android:clickable="false"
android:textSize="15sp" />
</LinearLayout>
<LinearLayout
android:id="@+id/id_tab_settings"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center"
android:orientation="vertical">
<ImageButton
android:id="@+id/id_tab_settings_img"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000"
android:clickable="false"
android:contentDescription="@string/app_name"
app:srcCompat="@drawable/tab_settings_normal" />
<TextView
android:id="@+id/textView4"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="設定"
android:gravity="center"
android:textColor="#ffffff"
android:clickable="false"
android:textSize="15sp" />
</LinearLayout>
</LinearLayout>
四、中間布局
四個tab.xml分別對應四個界面的中間內容，此處是第一個微信界面的，
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="horizontal">
<TextView
android:id="@+id/textView5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:layout_weight="1"
android:text="這是微信聊天界面"
android:textSize="25sp" />
</LinearLayout>
五、activity_main.xml
activity_main.xml里需要加上FrameLayout(重疊布局)和include
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="@layout/top" />
<FrameLayout
android:id="@+id/id_content"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</FrameLayout>
<include layout="@layout/bottom" />
</LinearLayout>
